Abstract

An apparatus, method, and computer program product are provided for determining a carrier to interference-noise ratio (CINR) and received signal strength indicator (RSSI) in a wireless communication system. A base station (302-304) calculates (506) a carrier power (C) of at least one user in the wireless communication system, and a noise interference (NI) (514) for one cell or sector in the wireless communication system. The carrier power (C) is divided by the noise interference (NI) to produce a value representative of the carrier to interference-noise ratio (C/NI). The received signal strength indicator (RSSI) is derived (510) by combining weighted carrier power (C) and noise interference (NI).
